Hello, Registration is now open for the meeting May meeting, which is in just over 2 weeks time and will be on a Wednesday this month. Cheers, Andrew // Event #34 — 21st May 2014, 17:30 - 20:30 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: http://oshug.org/event/34 The thirty-fourth OSHUG meeting will feature three talks that each explore approaches to teaching electronics and programming. — Teaching with the LilyPad Arduino In this talk we will hear about experiences of teaching basic electronics and coding principles via wearable technology and e-textiles, using the LilyPad Arduino — a sewable microcontroller — in workshops with people of all ages at universities, schools at hackspaces. Rain Ashford designs and constructs wearable technology, e-textiles and interactive artworks. A PhD candidate at Goldsmiths, where she is investigating the possibility that wearable technology can be used to augment new forms of non-verbal communication, particularly in the areas of body language and emotion, by the amplifying and visualising of physiological data. She has studied Fine Art, Multimedia, and Electronics Engineering, which has led to her work developing as a convergence of art, programming and electronics. — Raspberry Pi in education Challenges, benefits and experiences with the Raspberry Pi as an educational tool. Matt Venn has run hundreds of creative science workshops for thousands of children and adults around the world. For the last year, he has been working with teachers in preparation for the computer science curriculum changes; creating and leading courses, workshops and projects. When he's not inventing new ways of getting people excited about science, Matthew plays music, invents puzzle boxes, practices martial arts and maintains bikes. — MzTEK: festivals, workshops and take away technologies MzTEK is a non-profit organisation that aims to redress the imbalance of women artists working in the fields of new media, computer arts, electronics and technology. Based in London and supported by Hackney arts institution [ space ], and Centre for Creative Collaboration in Kings Cross, and hosting a range of workshops, talks and self-initiated tinker sessions. In collaboration with partner organisations, MzTEK develop interesting, accessible and curiosity igniting workshops that can be delivered in short time frames and engage a wide audience with varying skills. Working with open source technologies and tools to help ensure that participants continue making and tinkering with the technologies they encounter long after workshops. Furthermore, doing this at festivals and events where the hope is to encounter a broad range of participants and unpredictable work environments! This talk will discuss some previous projects such as the Hacked Human Orchestra, a wearable electronics project devised in collaboration with Guerrilla Science, and suggest ways that thematic focus, together with a well balanced combination of skill acquisition, creativity and fun can enhance workshop delivery. Shauna Concannon is an interdisciplinary researcher interested in communication spaces and constructive disagreement.

Open-source verification
by Chris Higgs 04 May '14

04 May '14

All, I would like to present on the topic "Cocotb" at a future OSHUG event. Cocotb[1] is an open-source Python framework for verifying RTL written in [System]Verilog or VHDL. It has been used to successfully verify multiple large FPGA designs (>500k registers). It also serves to bridge the gap between traditional FPGA/ASIC practices and software developers, as well as helping to introduce agile methodology and continuous integration to hardware teams. Cocotb works well with Icarus Verilog, providing a powerful open-source alternative to SystemVerilog based verification frameworks like UVM which require users to spend many thousands of pounds on simulator licenses. For those wishing to use SystemVerilog without paying for a license it can also be used with the free version of Mentor Modelsim (Altera Starter Edition). A presentation would be a good follow-up to the up-coming ChipHack event to demonstrate one of the possible ways of verifying more complex designs for those wishing to pursue FPGA development further. Depending on the experience and interests of the audience I can present different aspects of Cocotb, e.g. how the framework was designed, co-simulating unmodified software, interacting with the outside world from simulation, SoC driver development, lessons learned etc. Thanks, Chris [1] http://potentialventures.github.io/cocotb/

10A rated 5.5mm / 2.5mm DC barrel connector?
by Andrew Back 13 Apr '14

13 Apr '14

Hello, I'm having difficulty sourcing barrel connector sockets rated at >5A, which is bizarre as numerous reputable suppliers sell 12V/10A desktop PSUs that terminate in a 5.5mm OD / 2.5mm ID barrel plug. Yet, no matter how much searching I do I can only seem to turn up 2.5A rated sockets and, at a push, 5A rated. Grateful for any suggestions or insights anyone can offer here... Cheers, Andrew

OSHUG #33 -- Radio Pt.2 (Networking Literacy Project, Everyone has a radio in them)
by Andrew Back 02 Apr '14

02 Apr '14

Hello, Registration is now open for the April meeting. Details below. Cheers, Andrew // Event #33 -- Radio Pt.2 (Networking Literacy Project, Everyone has a radio in them) Thursday 24th April 2014, 17:30 - 20:30 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: http://oshug.org/event/33 The thirty-third OSHUG meeting will be the second on the theme of radio, with talks on a bold vision for a project that aims to increase understanding of personal networking, and on a toolkit that lets you build your own physical Internet radio. -- The Networking Literacy Project "Beep-BEEP!" - Some of us will remember the distinctive click when throwing the power switch of a BBC Micro, and the immediate gratifying sounds it made. Thirty years ago, public awareness of personal computing was low, and civil society acted to raise literacy in anticipation of the coming boom. Today, computers are pervasive in everyday life, and their function is increasingly to deliver distributed computing applications. Indeed, we are on the cusp of another era of personal technological progress and growth, this time for personal networking. Understanding and literacy about this is low, while importance and opportunity are high. This talk will explore some of the learning opportunities, and how the technology community could contribute to eliminating the widespread functional illiteracy in this important area of technology. Martin Geddes is an authority on the future of the telecoms industry, ranging from emerging business models to new network technologies. He is a futurologist, writer, speaker, consultant, and technologist. Martin is currently writing a book, The Internet is Just a Prototype, on the future of distributed computing. -- Everyone has a radio in them, it turns out Inspired by the challenge of making a physical radio device that did anything interesting and web friendly, a small team within BBC R&D spent a few days building an Archers Avoider using off the shelf components and free software alongside BBC created custom services for controlling audio IP streams. "Radiodan" is now at v2.0 and consists of open source web-developer-friendly software designed to work on a Raspberry Pi, used for controlling audio streams, getting a device on a wifi network, and controlling buttons, dials and leds, plus a kit of parts, a case and some instructions. This talk will take a look at some of Radiodan's technology, in the context of our goal of making it something that anyone can start to build a radio with. It will also explore why it's important and interesting to widen the pool of people who can make radios, and how a new field for us has changed the way we work. Libby Miller is a producer and developer working in the BBC R&D Central Lab. She currently works on Radiodan, a project about cheap, rapid prototyping for radios. She also works on the VistaTV EU project on the use and visualisation of real-time IPTV statistics, and the MediaScape project, which is about developer-friendly standards for connected devices. Before that, she led the BBC's part of NoTube, including work on APIs to TV for second screens, resolution of broadcast metadata to web metadata, synchronised social experiences, and recommendations and serendipity. Note: Please aim to by 18:15 as the first talk will start at 18:30 prompt.

MFS Meeting. Tue, 18 Mar. Talk: "The GNU Compiler Collection: How to Use, Port and Upstream the World's Most Widely Used Tool Chain"
by Michael Dorrington 27 Feb '14

27 Feb '14

Please feel free to forward this to those that would welcome it. * Event: Manchester Free Software's March Meeting * Talk: The GNU Compiler Collection: How to Use, Port and Upstream the World's Most Widely Used Tool Chain * Speaker: Dr Jeremy Bennett (Embecosm) (and Joern Rennecke (Embecosm) for Q&A) * Date: Tuesday, 18th March 2014 (3rd Tuesday of the month) * Start time: 19:00 * Finish time: 20:30 (and then on for drinks) * Location: Madlab. (Manchester Digital Laboratory). - http://madlab.org.uk/ * Address: 36-40 Edge Street, Manchester. M4 1HN. - Opposite "Common" on Edge Street, Northern Quarter. - http://www.openstreetmap.org/#map=19/53.48413/-2.23639 Details ------- The purpose of Manchester Free Software is to promote the Free Software philosophy. This meeting will be a talk with Q&A. "The GNU Compiler Collection (GCC) is 28 years old this year. Originally a C compiler, it now handles many languages (8 in the official distribution) and has been ported to many architectures (nearly 50 in the official distribution). Alongside the compiler are low level binary utilities (assembler, disassembler, linker, profiler, etc.) and a source level debugger (GDB). At 5 million lines of code, GCC is the third largest program in any GNU/Linux system. In this talk we'll look at how to best use the tool chain. Starting with official distributions, we'll look at what is needed to build your own version from source code. We'll then explore what it takes to modify the tool chain, to port it to a new architecture, to test it, and ultimately to have your code accepted into the official FSF distribution. We'll also look at some of the more unusual uses of the tool chain. Its porting to new chips during the design phase to test the hardware design before spinning silicon. How approaches such as iterative compilation and genetic algorithms can double performance compared to -O3. And finally how compilers can use machine learning to work out the best optimizations for your program and even optimize for energy efficiency. Throughout the talks we'll use practical examples from both native compilers (for Intel and ARM) and for cross compilers (such as Atmel AVR and Adapteva Epiphany). We'll also demonstrate the low cost free hardware energy measurement board used to optimize for energy efficiency." Speakers -------- "Dr Jeremy Bennett is Chief Executive of Embecosm, an free/libre and open source software consultancy specializing in tool chain development and silicon chip modelling. A former academic he is author of "Introduction to Compiling Techniques" (McGraw-Hill 1990, 1995, 2003). Joern Rennecke, who leads GCC development for Embecosm, will take questions at the end of the talk. Joern is one of the leading developers of GCC, a project to which he has been contributing for nearly 20 years. He has been responsible for the Renesas SH, OpenRISC 1000, Synopsys ARC ports and most recently has been developing the Atmel AVR and Adapteva Epiphany implementations. Embecosm are currently hiring both trainee and experienced compiler developers. Details at http://www.embecosm.com/careers/." After-meeting ------------- The meeting will be followed by informal discussion and socialising in the bar opposite, Common <http://www.aplacecalledcommon.co.uk/>. There are soft drinks available and there is no pressure to consume alcohol. Location -------- The meeting will take place at the usual venue of Madlab, details above. Ring the bell beside the door to be let in. The venue provides wifi. Parking ------- Around the venue there are parking meter bays that become zero cost after 8pm on Tuesday so you will have to pay up until then and the maximum stay is 2 hours BUT MAKE SURE YOU VERIFY ALL THIS on parking. There are paid parking lots around the venue, they are marked by a blue P in this OpenStreetMap centred on Madlab <http://www.openstreetmap.org/#map=15/53.4843/-2.2365>. Most of those parking lots are owned by NCP <http://www.ncp.co.uk/>. If you can’t decide otherwise then park in Manchester Arndale <http://www.manchesterarndale.com/directions.aspx>. Public Transport ---------------- Manchester Victoria (MCV) train station, Shudehill tram and bus station, and Manchester Piccadilly bus station are all fairly close to Madlab, see OpenStreetMap centred on Madlab <http://www.openstreetmap.org/#map=15/53.4843/-2.2365>. Manchester Piccadilly (MAN) train station and Manchester Central Coach Station are not too far away either.

OSHUG #32 -- Embedded Scripting, 27th March 2014.
by Andrew Back 27 Feb '14

27 Feb '14

Hello, Registration is now open for the March meeting. Details below. Regards, Andrew // Event #32 -- Embedded Scripting (Lua, Espruino, Micro Python) 27th March 2014, 17:30 - 20:30 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: http://oshug.org/event/32 The thirty-second OSHUG meeting will take a look at the use of scripting languages with deeply embedded computing platforms, which have much more constrained resources than the platforms which were originally targeted by the languages. -- Programming a microcontroller with Lua eLua is a full version of the Lua programming language for microcontrollers, running on bare metal. Lua provides a modern high level dynamicaly typed language, with first class functions, coroutines and an API for interacting with C code, and yet which is very small and can run in a memory constrained environment. This talk will cover the Lua language and microcontroller environment, and show it running on-off-the-shelf ARM Cortex boards as well as the Mizar32, an open hardware design built especially for eLua. Justin Cormack is a software developer based in London. He previously worked at a startup that built LED displays and retains a fondness for hardware. He organizes the London Lua User Group, which hosts talks on the Lua programming language. -- Bringing JavaScript to Microcontrollers This talk will discuss the benefits and challenges of running a modern scripting language on microcontrollers with extremely limited resources. In particular we will take a look at the Espruino JavaScript interpreter and how it addresses these challenges and manages to run in less than 8kB of RAM. Gordon Williams has developed software for companies such as Altera, Nokia, Microsoft and Lloyds Register, but has been working on the Espruino JavaScript interpreter for the last 18 months. In his free time he enjoys making things - from little gadgets to whole cars. -- Micro Python -- Python for microcontrollers Microcontrollers have recently become powerful enough to host high-level scripting languages and run meaningful programs written in them. In this talk we will explore the software and hardware of the Micro Python project, an open source implementation of Python 3 which aims to be as compatible as possible with CPython, whilst still fitting within the RAM and ROM constraints of a microcontroller. Many tricks are employed to put as much as possible within ROM, and to use the least RAM and minimal heap allocations as is feasible. The project was successfully funded via a Kickstarter campaign at the end of 2013, and the hardware is currently being manufactured at Jaltek Systems UK. Damien George is a theoretical physicist who likes to write compilers and build robots in his spare time. Note: Please aim to by 18:15 as the first talk will start at 18:30 prompt.

OpenData + Wearable devices hackathon! 15-16th March at TechHub, Manchester.
by Andrew Back 13 Feb '14

13 Feb '14

Hello, Details below of an open data/wearables hackathon that may be of interest to folks. Cheers, Andrew // OpenData + Wearable devices hackathon! 15-16th March at TechHub, Manchester. Open Data - Wearable devices - HACK! Registration: https://www.eventbrite.co.uk/e/numbers-that-matter-hackathon-tickets-103683… - What? We've done our studies. We've transcribed audio, shadowed people, documented their stories, captured their concerns, and been receptive to their ideas. We have a body of work relating to what kind of numbers matter to them, how we could realise them, and what kind of devices would work in the field. This leads to our hackathon. We have a body of documentation we'll make available about what people want, how they understand and relate to data around them, and ideas for possible devices. You'll be able to explore and help realise these ideas - either as they are, or from your own perspective. We'll have equipment for you to use, from Raspberry Pis to Arduinos, and experts on-hand who will help you get to prototype. The overall winner from the day, as voted for by a panel of judges, will win the opportunity to take their prototype to a full field trial with support from the Numbers That Matter team. - Who We encourage collaboration between participants - if you don't already have a team to work with, you can meet up with people at the start of the event. It's easier to complete a hack if there's a range of skills and people working together. We'll be making working prototypes of hardware and software on the day, so people with experience in these fields are important team members. Design is a key aspect of usable devices and experiences - teams will need these skills to anticipate and plan meaningful devices Analysis and data processing skills will be needed in your team - knowledge of existing formats and platforms can speed development on the day Entry is open to anyone; professional developers, activist hackers, design students, anthropologists, sociologists, geeks and social entrepreneurs are welcome, as is anyone who feels they can contribute to the day.

Fixing a date for OSHCamp 2014.
by Andrew Back 07 Feb '14

07 Feb '14

Hi All, Last year's OSHCamp was something of an experiment — hosting it as part of Wuthering Bytes — and based on how the event went overall and feedback, we've decided to do something a bit different this year. The idea is that OSHCamp will still be hosted as part of Wuthering Bytes, but that the latter will become more of a festival comprised of a series of events: * OSHCamp will have the Waterfront Hall to itself on the Saturday (10x talks) and Sunday (workshops). * On the Friday there will be a day of talks in the Waterfront Hall on a much broader range of topics (think of the non-OSHUG and crossover talks from WB 2013), with accompanying workshops upstairs in The Space on the Saturday. * Main social event Friday evening. * A number of smaller/fringe events in the week leading up. The dates we are looking at are: August 15/16/17 September 19/20/21 And ideally we need to decide on August or September ASAP. So, any preferences? Improved chances of better weather in August, but obviously a lot of people go away on holiday. Which may not be a bad thing, if you want to take a break in Hebden Bridge :o) Best, Andrew

OSHUG #31 — Privacy and Security, 20th February 2014.
by Andrew Back 22 Jan '14

22 Jan '14

Hello, Registration is now open for the first OSHUG meeting of 2014! Details below. Regards, Andrew // Event #31 — Privacy and Security (Security protocols in constrained environments, RFIDler, Indie Phone) 20th February 2014, 17:30 - 20:30 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: http://oshug.org/event/31 The thirty-first OSHUG meeting is dedicated to privacy and security, with talks on implementing security protocols in constrained environments, an SDR RFID reader/writer/emulator, and a new initiative that will use design thinking and open source to create a truly empowering mobile phone. — Security protocols in constrained environments Implementation of security protocols such as TLS, SSH or IPsec come with a memory and compute overhead. Whilst this has become negligible in full scale environments it's still a real issue for hobbyist and embedded developers. This presentation will look at the sources of the overheads, what can be done to minimise them, and what sort of hardware platforms can be made to absorb them. The benefits and potential pitfalls of hardware specific implementations will also be examined. Chris Swan is CTO at CohesiveFT where he helps build secure cloud based networks. He's previously been a security guy at large Swiss banks, and before that was a Weapon Engineering Officer in the Royal Navy. Chris has tinkered with electronics since pre-school, and these days has a desk littered with various dev boards and projects. — RFIDler: A Software Defined RFID Reader/Writer/Emulator Software Defined Radio has been quietly revolutionising the world of RF. However, the same revolution has not yet taken place in RFID. The proliferation of RFID/NFC devices means that it is unlikely that you will not interact with one such device or another on a daily basis. Whether it’s your car key, door entry card, transport card, contactless credit card, passport, etc. you almost certainly have one in your pocket right now! RFIDler is a new project, created by Aperture Labs, designed to bring the world of Software Defined Radio into the RFID spectrum. We have created a small, open source, cheap to build platform that allows any suitably powerful microprocessor access to the raw data created by the over-the-air conversation between tag and reader coil.

OSHUG #31 - 20th Feb.
by Andrew Back 06 Jan '14

Hi All, Firstly, save the date: the first meeting of 2014 will take place on Thursday 20th February. The theme is going to be along the lines of security/privacy and there are two talks already confirmed and looking for a third. I was wondering if anyone knew someone who was involved with the FreedomBox project, or perhaps knew enough about it to give a talk on it themselves? Suggestions of other device and networks security and privacy related talks are also welcomed. Cheers, Andrew
